CLOCK-MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 257,025, dated April 25, 1882.

Application filed January :25, 1882. (No model.)

To all whom it may concern:

Be it known that'l, FRED. A. LANE, of New Haven,in the county of New Haven and State of Connecticut, have invented a new Improvement in Clock- Movements; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be afull, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l a front View; Fig. 2, a side view.

This invention relates to an improvement in clock movements, particularly to that class which are designed for very small cases-such, for illustration, as that known in the market as the Yale Gem -the object being to adapt marine movements to this class of clocks; and

.it consists in a movement having a vertical division-plate between the front and rear plates, the main-wheel shaft taking its bearing in said division-plate and rear plate, the main-wheel spring and center pinion arranged between said division and rear plates, the balance-wheel outside the division-plate and in front on the main wheel, as more fully hereinafter described.

A represents the rear plate; B, the front plate, which is shorter than the rear plate-say by one-half its length.

B is the vertical division-plate,arranged-between the front and rear plates, and substantially the same size as the rear plate,the three plates connected together by pillars D in the usual manner,'so that each is held in its proper relative position to the other.

E is the mainwheel shaft, which takes its bearing in the rear plate,-A, and division-plate O, the main wheel F and the spring G arranged on the said shaft in substantially the usual manner, and between the rear plate and the division-plate, as seen in Fig. 2.

H is the center shaft, taking its bearing in the rear and front plates and exten din g thron gh the division-plate. It is provided with a pin- 5 ion, I, between the rear and division plates, into which the main wheel works, and from which the train of gearing which is arranged between the division-plate and the front plate is operated.

a is the balance=-wheel, its shaft taking its bearing in the division-plate C, as at b, and in arm, (1, extending down from the front plate, so that the balance-wheel stands in front of the main wheel and in rear of the plane of the front plate. The balance-wheel operates upon the crown wheel 0 through a lever, f, in the usual manner.

By employing a division-plate and arranging the main wheel and its spring upon one side of that plate and the balance-wheel on opposite side I am enabled to bring the balance-wheel and its connecting mechanism in front of the main wheel and within the limits of the space necessary for that main wheel. Themain wheel is shown in broken lines, Fig. 1 At the same time the front plate is made so short that the balance-wheel and its immediate connections are exposed so that they may be seen through an opening in the clock-case, thus imparting an attraction to the little clock which a pendulum cannot do.

I claim- The combination, in a clock-movement, of a plate forming the rear bearing of the main and center wheel shafts, a center plate forming a front bearing for the main-wheel shaft, and rear bearings for the shafts of the train and balance-wheel,- the short front plate forming front bearings for the shafts of the center wheel and train, and a support for the front end of the balance wheel shaft, all substantially as described.
